Patent DE-2345161-A1 (DE)
Title: Chlorinated hydrocarbons for textile cleaning regenerated - by distillation cooling settling and filtration using steam
Inventor: GENZ WILHELM
IPC: B01D3/00
Filed: 1973-09-07
Abstract: Continuous distillation clarification is used for regenerating chlorinated hydrocarbons for the chemical cleaning of textiles. The plant comprises a steam generator and distillation vessel sharing a common heater below them. Steam passes directly from boiler to distillation vessel. Solvent enters and passes through an activated charcoal filter and then into the distillation vessel. Solvent-steam mixture leaves this vessel and is cooled and liquefied, then passes to a settling tank where the lighter water leaves and the heavier solvent passes through an adsorption filter to a collecting tank for subsequent re-use.

Title: Formation of groups of bags or sacks - stack pushed into shaft gap and packed in flat roll
Inventor: ROCHLA KURT
IPC: B65B63/04
Filed: 1973-11-14
Abstract: Packable group of bags or sacks are formed by stacking them, lying flat, and pressing the stack in the region of its transverse midline through a gap delimited by lateral supports into a shaft which folds in the floor and filling side parts of the bags, aligned on the shaft sidewalls. The flat roll thus formed is packaged. Pref. the apparatus has a shaft open at least one end and of width corresp. to approx 1/3 of the bag length plus twice the stack height. The shaft can be partially closed by a removable floor, and a pusher can be lowered in above the stack and also can travel horizontally in and out. There are two further similar pushers within the shaft, and when the pusher is lowered the vertical spacing between shaft floor, pusher and each of the lateral pushers corresponds respectively to the height of a stack.

Title: Energy extraction from sea and earth - spiral funnel tunnel construction exploits water pressure and earth heat
Inventor: FOPPE WERNER
IPC: F03G7/04
Filed: 1973-12-14
Abstract: In the upper part of a drop shaft the potential energy of falling sea water is utilized using several, series connected, high pressure water turbines. This sea water, under the pressure of the fresh water column in the lower part of the drop shaft, is super-heated by the geothermal heat in the heating shaft and is brought to double its volume so that the counter-pressure column in the climb shaft attains double the height of the fresh water column in the drop shaft. The sea water is lifted above its drop height and the energy extraction process can go on to a larger scale using high pressure water and steam turbines. The transport and supply tunnels as well as the transverse coupling tunnels cut the tunnel spiral thereby allowing the introduction of several simultaneously working drilling machines.

Title: Mechanical handling equipment - for hides, skins,etc. in a tannery
Inventor: DOKOUPIL JIRI DIPL ING
IPC: C14B1/62
Filed: 1974-02-18
Abstract: Manipulation of heavy hides in a tannery, present in trucks, containers or large heaps by (i) fixing at least two clips (self-closing tongs) provided on the ends of two flexible elements e.g. ropes, chains etc., to the edges of a skin. (ii) after an operating signal, pulling these elements vertically and then horizontally or with both motions simultaneously, in such a way that the skin is released from the heap and transported with the grain or flesh side upwards or downwards by such motion onto a table rotatable about a vertical axis. (iii) after opening the clips orienting the skin by means of the rotatable table in the direction required e.g. for further processing in a machine. Process saves labour and largely eliminates the physical efforts of handling heavy skins and hides, which can weigh 70-80 kg.

Title: Mounting for HF electromechanical filters - gives high stability for thin piezoelectric slices and convenient construction of multielement filters
Inventor: KOHLBACHER GERHARD DIPL ING
IPC: H03H9/60
Filed: 1974-02-28
Abstract: A method of mounting the thin piezoelectric slice elements in high frequency electromechanical filters is presented, in which good mechanical stability and protection against fracture are attained. Basically the thin slice is held between two conducting plates which are soldered, glued or welded together. In one plate a rectangular hole, and in the other plate a circular, smaller hole, expose the piezoelectric slice and allow electrodes to be attached via connectors to two terminals. Quartz crystal is usually used as the piezoelectric element and this can be as thin as 33muM or 33 mu.m for frequency characteristics up to 150 MHz. Clamping holes enable a number of such units to be clamped together.

Title: Pliers type staple binder - has lever operating clinching jaws on frame
Inventor: HOSAKA HIDEO
IPC: B65B51/04
Filed: 1974-06-19
Abstract: The binder has a pair of opposed clincher jaws pivotally mounted on a frame. The jaws are connected to and movable between open and closed positions by a sliding member which is moved by an operating handle pivotally mounted on the frame. The operating handle is swingably movable within a plane which is substantially perpendicular to a plane defined by the movement of the clincher jaws. A removable magazine is fitted within the frame and contains staples, with the front most staple being positioned between the clincher jaws to be deformed around the object. The arrangement provides improved visibility of the work as the handle does not operate in the same direction of the staple.

Title: Automatic extending car bumper - with pneumatic cushions inflated w.r.t. engine speed by connected air pump
Inventor: BASHIR-ELAHI SOHRAB
IPC: B60R19/18
Filed: 1975-05-28
Abstract: The padded car bumper is braced on the car body by one or more flexible tubes. The tubes are connected to an air- pump driven off the engine with the output pressure of the pump corresponding to the engine speed, or road speed. As the vehicle is driven faster the pressure increases and the tubes are inflated harder. The spacing of the bumper from the car body thus increases with speed, and increases the impact absorbing capability of the bumper.
